Skin-core polypropylene composite plastic high imitation rattan and preparation method thereof

Abstract

The invention discloses a skin-core polypropylene composite plastic high imitation rattan and a preparation method thereof. The high imitation rattan is prepared by the steps of: a. mixing a polypropylene matrix, a toughening agent, a compatilizer, a physical foaming agent, an antioxidant and a pigment, then conducting melt extrusion and foaming to obtain a foamed polypropylene rattan-imitating substrate; b. adding a soluble pore-forming agent, straw glue and inorganic whisker into an organic solvent to prepare a viscous outer wall solution; and c. impregnating the rattan-imitating substrate in the outer wall solution, then conducting washing and drying curing, thus obtaining the skin-core polypropylene composite plastic high imitation rattan. The method has the beneficial effects that: the high imitation rattan prepared by the method provided by the invention has a rough and matt surface, has appearance, texture and density similar to those of natural rattan, also has soft texture like natural rattan, completely achieves the performance of natural rattan, at the same time has high tensile strength and folding endurance, good mechanical properties and good durability, thus having wide application range.

Description

technical field [0001] The invention relates to the field of preparation of rattan-like materials, in particular to a skin-core polypropylene composite plastic high-like rattan and a preparation method thereof. Background technique [0002] Natural rattan has certain mechanical properties, and its color is simple and natural. It is the main material for fabricating daily necessities such as furniture, baskets, boxes, and frames. However, natural rattan tends to reduce its strength after being exposed to moisture, and is prone to mold and rot, so the products processed by it are not suitable for outdoor use. In addition, the extensive use of natural rattan may cause ecological damage, and the treatment process before weaving is complicated, which greatly limits its practical application. [0003] Polymer materials have a wide range of sources, easy processing, high mechanical properties, light weight, etc., and are widely used in daily necessities, especially polyolefin poly...

AI Technical Summary

Problems solved by technology

[0008] It can be seen that the biggest disadvantage of plastic imitation rattan in the prior art is poor texture, and its woven products are far from the characteristics of natural rattan close to nature, so it is difficult to use it as high-end furniture and handicrafts indoors

At the same time, the mechanical properties of some imitation rattan materials are not ideal. At the same time, the filler has a great influence on the bending resistance of rattan. During the weaving process, there will be obvious stress cracking and whitening, which will affect its use effect.
